The foreach statement works because you are getting the array index
($k) to unset the array item. I think somewhere in the manual it says
it's unsafe because some people might think you could just use unset
($v) to unset the array item. Which wouldn't work because $v is more
of a temporary v

Why should this be "unsafe" (whatever the heck that means) in any way? Of
course you can do it.

Somewhere in the manual (damned if I can find it now) it says (or used
to say) that you can or can't safely do this:
while (list($k, $v) = each($array)){
if (...) unset($array[$k]);
}
I don't even remember if it's safe or not, but I swear I saw it not

Anyway, can you do *this*
